GUAIHJD FR TEXTILE MAI'IINEEY.

Application filed May 121, 1917.

To all whom t may concern:

Be it known that we, JAMES. F. Beinen and CORNELIUS d. HARTMAN, citizens oii' the lUnited States, residing at Scranton, in the county of Ilackawanna and State ot' Pennsylvania, have invented certain new and useful Improvements in Guards iler Textile Machinery, et which the following is a specification.

'I his invention relates to a guard tor tex tile machinery, and we have shown the same applied to what is known as the -B twisting and doubling machine made by the Atwood Machine Company, showing only so much thereof as will illustrate the position occupied by and the use et the guard. It will of course be understood that a large number of the guards are employed on each complete machine.

The object oi'l the guard or shield is to prevent the silk from winding around the driving shaft. A. special advantage of the guard as used by us is that it can be put on without tools or employing any fastening devices, and can be lit'ted ed readily to get at the gears.

In the accompanying` drawings,

Figure 1 is a side elevation showing a portion of the machine, the saddle, saddle bracket and rollers, with the guard in position.

Fig. 2 is a liront view.

Fig. 3 is a section on the line 3-3 of Fig. 1, the saddle being removed.

Fig. 11 is a perspective view ot one ot the guards, detached.

In the drawing 1 designates the saddle, 2 the saddle bracket, 3 the rollers and l the gears, carried by the saddle and supported with the saddle on the bracket, and 5 are uprights carried by the bracket. The driving roller 6 is provided with a gear 7 which meshes with the gears 4l. 8 is the rod supporting the bracket and 9 the spring that disengages the gears e from the gear 7 on the breaking of a thread.

@ur guard consists of a plate 10 which is pressed outwardly at 11 thereby forming on the inner tace et the guard a longitudinally extending channel adapted to receive the gear 7.

At its upper end the plate 10 is bent to torni an integral, horizontal flange 12. The central portion et the flange lies in the hori- :rental plane of the upper edge of the body Specification of Letters Patent.

serial no. 16a/loa i portion of the plate 10 while the marginal portions 13 and 13a are oitset or elevated forming side ribs. The liange 12 is transversely cut as at lll forming a slot that registers with the upper end et the channel 1l and through which the gears a and gear 7 mesh. lhe ribs are slotted as at 15 to lit over the uprights 5 of the bracket. The course of the thread is indicated at 16.

It will be noted that the guard at the sides extends beyond the bracket.

To put the guard on it is only necessary to lil't up the saddle, thereby removing the rollers 3, and slip the guard into place the slots receiving the uprights 5, and it is held in place by the uprights and by the saddle.

To litt oil" the operation is practically as simple, the saddle being lifted ott and then the shield simply slipped over the uprights giving innnediate access to the gear 7 and the drive shalt. lfhe guards are made ot tin, and are cheap, durable and a boy can put them in place.

What we claim is:

1. In a device of the kind described, the combination with a saddle and saddle bracket, the latter having uprights, et a guard adapted to rest beneath the saddle, said guard comprising a tlange held between the saddle and the bracket and slotted to lit over said uprights.

2. In combination with a twisting and doubling machine having a drive roller, a gear thereon, a saddle bracket having uprights, a saddle, and rollers and gears carried by the saddle, of a flanged guard, the flange being slotted to permit meshing ot the gears, and slotted to lit over said up rights, said flange when in position resting between the bracket and the saddle, and held in place by said uprights.

3. A. guard of the kind described comprising a plate having a longitudinal gear receiving channel `formed on its inner tace and flanged at one end, said flange having slotted elevated side marginal ribs, and the flange being slotted in alinement with the channel ot the plate lirst mentioned, as and for the purpose set forth.

In testimony whereot we atllx our signatures.
